Delaware County Coroner Scott Hahn said autopsies were conducted. An official cause of death is awaiting toxicology tests, but the coroner said there was “no sign of trauma.”

A witness told officers he was aware Rudisill had ingested heroin purchased from Campbell on Monday evening and believed she had collapsed after ingesting a second dose early Tuesday.

According to an affidavit, a man found with Campbell told investigators they “have a drug problem and deal crystal meth and heroin to support their drug addictions and living expenses.”

He acknowledged that in separate visits to the Muncie house where Rudisill later overdosed, Campbell had twice sold her heroin, for $40 and $20.

He also said after learning of Rudisill’s death, he and Campbell “panicked and left Muncie and found a hotel room in Anderson,” where they “rehearsed a story” denying any knowledge of the events leading to the overdose.

The affidavit reflected officers had reviewed phone records and text messages, and that "the last phone call made from Ashley's phone (was) to Jessica's phone."

Campbell was being held in the Delaware County jail without bond.

Chief Deputy Prosecutor Zach Craig said the charge against her stems from a new state law that went into effect July 1.

An affidavit listed two such charges against Campbell, but Craig said he was not certain the new law would apply to an unborn child’s death.

“There is a feticide statute, but for that to be applicable,” a defendant would have had to “knowingly and intentionally” caused that death, the chief deputy prosecutor said.

Craig said the new statute specifies it is “not a defense that the individual voluntarily used the drug,” or facilitated their death by mixing that substance with alcohol.

“The dealer gets that victim as they come to them,” he said. “I think it makes it that much stronger of a statute.”

Craig said he did not believe this week’s investigation was conducted differently because of the unborn infant’s death.

“Obviously there’s an emotional element present in this type of overdose death that you don’t see typically,” he acknowledged.

On July 20, the prosecutor’s office charged Rachelle L. Tucker, a 30-year-old Muncie nurse, with murder in a July 2017 overdose death.

Authorities allege Tucker sold that victim, 29-year-old Dustin Richard Rhodes, heroin, and then ordered an associate to remove Rhodes from the area of her home after he began to overdose. His body was later found near a southside intersection.

“We’ve really in the last year tried to make an effort to change how these investigations go,” Craig said. “For years, (an overdose) was kind of looked at like an accidental death investigation.”

Campbell’s criminal record includes convictions for possession of a controlled substance, possession of a look-alike substance and theft.

Rudisill also had a history of drug-related arrests. As recently as June 14, the Muncie woman was sentenced to time already served in jail after she pleaded guilty to possession of a narcotic drug.
